BELLOWS.

Application filed January 20, 1908.

To all whom "it may concern:

Be it known that I, EDWARD PARO, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Bellows, of which thefollowtion.

ing is a specification.

Bellows, as commonly constructed, have a nozzle attached or connected tothe leather or flexible sides of the air chamber, and this constructionhas the defect that leaks are apt to occur where the said flexiblematerial. is joined to the nozzle.

The object of the present invention is to avoid this defect, and thisobject is effected by mounting the nozzle upon one of the plates, with ahole therethrough leading to the nozzle.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a plan view of a bellows so constructed. Fig. 2 is a sideview partly in sec- Fig. 3 is a detail of the nozzle removed from thebellows.

Referring specifically to the drawings, 6

and it has a depending nipple 13 which fits within. a hole formed in theplate 6 to receive it. One of the plates has the usual inlet valve 14therein, and the nozzle has a suitable outlet valve 15 therein, whichoperate in a well known manner.

By the construction shown the leather sides 9 may extend continuouslyaround the plates and have no joints subject to wear and strain incidentto the manipulation of the device. In the old construction the continuedbend of the leather where it was joined to the nozzle piece soonresulted in cracks and leakage around the mouth, but by mounting thenozzle upon one of the plates this objectionable result is avoided, andthe bellows will last indefinitely. The construction is alsoconsiderably cheaper, and particularly a saving of time and labor iseffected in assembling the parts.

I claim:

A bellows provided witha hole in one of the plates thereof, and a nozzlecomprising a base mounted on the plate and fastened thereto around saidhole, a nipple projecting inwardly from the base into said hole, a pipeprojecting outwardly from the base, and an outlet valve in the nozzle,between the nipple and the pipe.

In testimony whereof I aflix my signature, in presence of two witnesses.

EDWARD PARO.
